President Obama may have danced the electric slide with Chris Rock last night

President Obama marked his 50th birthday with a major fundraising swing through Chicago, but it turns out that wasn't his only celebration.

Last night, the president celebrated his actual birthday with a celebrity-studded party at the White House. The event, which wasn't listed on the president's daily schedule, featured a "surprise" performance by Stevie Wonder and an A-list guest list that included rapper Jay-Z, comedian Chris Rock, actors Tom Hanks and Whoopi Goldberg and former NBA stars Grant Hill and Charles Barkley.

The party came to light after Rock posted a message on Twitter about the gala, mentioning that guests had performed the "electric slide."

"A great night," he wrote.

Also in attendance, according to the blog Obamafoodorama: Many of Washington's top politicians, including Secretary of State Hillary Clinton, House Minority Leader Nancy Pelosi and Senate Majority Leader Harry Reid, as well as several of Obama's friends, staffers and top supporters.

The event was held in the Rose Garden and later moved into the East Room, where attendees danced to a DJ. According to reports, Thursday's menu included hamburgers, barbecue chicken and ribs and hot dogs, along with birthday cake and four different kinds of pie: cherry, huckleberry, peach and apple.

A White House spokesman says the gala wasn't included on the president's schedule because it was a private event and was paid for by the Obama family. But it was also likely kept quiet amid this week's troubling economic news, given a massive party might not play well with Americans struggling to make ends meet.

Indeed, some of Obama's conservative critics have taken aim at the party. As Daily Intel reports, Fox News published a questionable headline about the event: "Obama's Hip Hop BBQ Didn't Create Jobs."
